Fixed #6650: Recurring events are generated in weekview with allDayHeader

Version 6.0.0, 2018-08-10

We are proud to present the 6.0 release of our Scheduler for Ext JS. In this release you will find a lot of enhancements and bug fixes, as well as support for Ext JS 6.6. There are also
a number of breaking changes as part of our house cleaning (mainly in our internal classes, please see "BREAKING API CHANGES" section below for details). Starting with this release, we no longer support IE8, IE9 or IE10.

Here are some tips that might help you to migrate to 6.6.0:
Please be aware of Sencha has introduced strict JSON validation when loading the AJAX proxy. Your server should return a valid JSON format.
Using the native JSON any date object will be converted to ISO 8601 UTC format ("2018-01-01T06:00:00.000Z"), however you are safe since model field's dateFormat is configured as "c". If you wish to follow the native JSON standard, you may change the dateFormat to "C".
Ext CRUD operations now destroyable, so you need to process your response as soon as possible, until the operation is destroyed and data is cleaned up.

FEATURES / ENHANCEMENTS

Added support of recurring events. See the "Recurring events" guide for details.

Added a new JavaScript-based backend service for the export plugin which can be found in the `examples/export/server` folder. This solution uses Puppeteer as a headless browser and renders high quality PDF and PNG streams (#Fixed 3167).

The split plugin is now a supported plugin - `Sch.plugin.Split` (Fixed #5683).

The summary row plugin is now a supported plugin - `Sch.plugin.SummaryRow` (Fixed #5764).

Added new demo `resourcecollapsing` showing events overlapping by default, with option to expand each resource row to show all events in full.

BREAKING API CHANGES

`Sch.view.dependency.DropZone` class has been turned to private (Fixed #4300).

`Sch.plugin.EditorWindow` class `showRecord` method does not support `deleteOnCancel` flag as one of options of the second argument. This flag is not relevant since record is not created before the first saving anymore.

The first parameter of event `beforeeventdropfinalize` in `Sch.mixin.SchedulerView` is changed to `Sch.mixin.SchedulerView` instance. In 5.x `Sch.feature.SchedulerDragZone` used to be the first argument (Fixed #6479).
